  • Projector having scanning optics
    Patent number: 7184104
    Abstract: A projector that employs scanning optics is disclosed. A number of light-emitting sources have intensities that are varied in accordance with an image. The scanning optics scan the light output by the light-emitting sources to cover a two-dimensional plane in accordance with an image.
    Type: Grant

  • Double dotting for grain equalization
    Patent number: 7093918
    Abstract: This invention relates to a method for grain equalization utilizing double dotting, comprising the steps of: determining a drop weight of each die in a multi-die printhead to print a given ink; determining the highest drop weight amongst all the dies; and determining a percentage of double dotting that is needed to substantially match a grain of the highest drop weight die.

  • System and method for producing efficient ink drop overlap filled with a pseudo hexagonal grid pattern
    Patent number: 7014295
    Abstract: The present invention is embodied in a system and method for producing efficient ink drop overlap filled with a pseudo hexagonal grid pattern. In general, the present invention can include an inkjet printhead assembly that incorporates a preprogrammed correction scheme or schemes [1-n] (herein correction scheme will refer to all applications), for correcting systematic ink drop placement errors of the inkjet printhead. The printing system of the present invention uses a unique ink dot pattern, called a pseudo-hexagonal close pack system. The present invention optimizes the addressable grid for dot placement, pseudo hexagonal close pack system, with an efficient geometry for packing circles to fill an area, similar to the hexagonal close pack system. However, the present invention in creating dots on a non-symmetric grid is supported by available software and is not computationally complex.
